Answer:
x + √x - 6
Step-by-step explanation:
Multiply out (√x-2)(√x+3) using the FOIL method:
Multiply the First terms: x
Multiply the Outside terms: 3√x
Multiply the Inside terms: -2√x
Multiply the Last terms: -6
Now combine these results. We get:
x + √x - 6
Answer:
H = 120°
Step-by-step explanation:
The sum of the internal angles of a polygon with n sides is given by the formula:
S = (n-2)*180
So, for a pentagon, we have n = 5, then:
S = (5-2)*180 = 540°
So we have that:
M + A + T + H + S = 540° (eq1)
M = T = H (eq2)
A + S = 180° (eq3)
Using the second and third equation in the first one, we have:
H + H + H + 180 = 540
3H = 360
H = 120°
